Whats the MPG for you different V6 mustangs. One guy with gas saving mods claimed to get 30 MPG heres what he said,

"I can usually get about 420+ miles to a full tank on road trips. 15 gallon tank equals 28+mpg."

Is this possible?

i have heard of people getting 30+ mpg on their stangs. as for me the best highway mpg i have got is 26mpg and the average street mpg i get is 17 to 18 mpg. i floor my car a lot tho so thats probably why i get that ****** mpg with my "fuel efficient" mods.

I was getting 30-35mpg on long roadtrips in my 97 V6. I drove to Tennessee & back twice. The oly mods I had are the ones in my signature.

Wow, I wish I would have thought to check MPG before AND after when I installed my Mach 1 chin spoiler! Didn't even dawn on me to see if aerodynamics would effect MPG, and I know better! I was Naval Air (USS J F Kennedy CV-67), avid warbird junkie and balsa model aircraft builder. You'd have thought I would have been curious about ground effect, wind drag and resistance before the install, and it never crossed my mind. I just bought the spoiler to take care of that 'underbite' stock look.
I did notice that when I went from P245-45-19 tires to P245-35-19, I lost from 24MPG to 22ish.

my 35mpg was at 70-75 average and very few spots of up to 80/85. I had the cruise control on pretty much the entire time as well.

What size exhaust are you running? If you go too big you lose torque, which means you have to use more gas to get moving.

Yes 2 inch is stock.

Right, but it's dual . .. .

regardless, that shouldn't matter if it's 2"-


Ah, Got it! Your AC is on all the time.

Bump your tire pressure by 5 lbs and it will help a little.

my co-worker says when his tires are low he gets like 25-30 miles less out of a tank of gas. I don't know how accurate this is, but if it is, i am defiantly checking my tires daily :hihi:

Oh yeah, Tire inflation, too.

I just returned from vacation. I set the tripometer at the pump and after running 240 miles on the first leg of the trip i had just used a hair over half a tank, I think that comes out to around 30MPG it was all highway and I only ran A/C during the popup rainstorms since I had to roll up the windows. Average speeds were anywhere between 70-90 MPH ... gotta love that 5th gear :hihi:

I have the exact same set up as you with the exhaust and about to add the CAI next week. Does the CAI make that big a difference cuz Im only getting 240 for my whole tank.

I get 22 average with my mods. Won't be as good when I get my 3.73's installed next week though.

Hi Guys,

I am from the Netherlands (europe) and I recently bought a 1996 Mustang V6 (automatic)

I read a couple of things in this thread about getting better mileage thru some mods.

Since gas is 3 times as expensive over here as in the US I am REALY interested in those mods.

Can you please help me out and teach me about the mods and a good source for finding them?

Thanks in advance!

I need to also check into some mods, I recently went up to Roebling Road Raceway from Tallahassee Fl (315 miles) and barely made it on one tank of gas...roughly 21mpg(?). That was 75-85mph and picking up a bit of a draft off of big rigs most of the way.
